Value line of the desired signal
Use the up/down arrows on the LHMI to change the signal value or the appropriate menu in
PCM600.
The status of the signal changes automatically to Forced (i.e. there is no need to set the status
to Forced manually).
On the LHMI, these edit changes have immediate effect. This means that the value
changes directly when the up/down arrow is pressed (i.e. there is no need to press the
Enter key to effectuate the change).
